IMPROVEMENT IN HARVESTER-RAKES.

Specification forming part of Letters Patent No. 78,700, dated June 9, 1868.

To all whom 'it may concern:

Be it known that I, JOHN UNDERwooD, of Muscatine, in the county of Muscatine and State of Iowa, have invented certain new and useful Improvements on Rakes and Binding v Attachments for Harvesting-Machines; and I do hereby declare that thepfollowing is a full, clear, and exact description thereof, reference being hadto the accompanying drawings, making a part of this specification, in which- Figure 1 is al perspective view of themachine as seen from the front grain-sidecorner thereof. Fig. 2 is an elevation of the inner side of the raking and binding attachment. Fig. 3 is a top view of the upper platform and a portion of the curved grain-receiver.

Similar letters of reference indicate corresponding parts in the several figures.

This invention `relates to certain novel improvements on machinery which is designed for being attached to reaping machinery for gathering or reeling in grain to the cutting apparatus, and delivering the grain in gavels in a position where it Will be convenient for binding it in gavels by hand previously to discharging the gavels upon the ground.

The invention provides for attaching to a single or double wheel draft-frame a verticallyrevolving gathering and raking device, a curved grain-receiver with an elevated platform, and a laterally-reciprocatin g follower, all of which are so constructed and arranged that during the forward movements of the machine in cutting grain the grain will be pressed up to the cutters, and after being cut it will be moved backward and upward and delivered upon a platform, from which it will be moved laterally toward the inner side of this platform to a position for being bound by hand, as will be hereinafter described.

The invention further provides for locating a stand or seat, or both, for a binder upon the inner end or side of an elevated platform, which has a laterally-reciprocating follower applied to it, and which receives the cut grain from a grain-receiver, which is concentric with the axis of motion of a vertically revolving combined gatherer and raking device, so that a person sitting or standing in rear of the cutting apparatus will have the cut grain brought to him in a position which will be convenient for him to bind and deliver the bundles upon the ground out of the way of the team in cutting the succeeding swath, as will be hereinafter described.

The invention also provides for automatically moving the rake-teeth of a combined rake and gatherer, which revolves in the path of a vertical plane, and delivers the cut grain upon an elevated platform, so that said teeth will sweep over the grain-receiver in a position perpendicular thereto, and then turn so as to deliver the grain upon said platform, as will be hereinafter described.

vTo enable others skilled in the art to understand my invention, I will describe its `construction and operation.

In the accompanying drawings, A repre- "sents a finger-bar of a reaping-machine, which may be attached, in any suitable manner, to a draft-frame having either one or two transporting-wheels. The lingers and sickle are not represented in the drawings, for the reason that these parts may be constructed in any wellknown manner.

Upon this finger-bar A, and at or near the extremities'thereof, two posts, E E', are erected perpendicularly, which are suitably braced and adapted for sustaining a rotary shaft, F, carrying a combined grain gatherer and rake, which will be hereinafter described. To this finger-bar A a grain-receiver, B, is suitably secured, which extends backward and upward, and is concentric with the axis of motioiJ of the rake and gatherer shaft F, as shown in Figs. l and 2. This grain-receiver is provided on bothv sides with raised fenders or grainguards B1 B1, which may be parallel toI each other, or they may diverge toward the lingerbar, so that the concave grain-receiver B may be somewhat wider at its front end than it is at its rear elevated end.

By making the grain receiver B concave and concentric with the axis of the shaft F, as described, I accomplish two very important objects, viz: I am enabled to employ a very simple rake and gatherer, which will, during a part of its revolution, carry the cut grain backward a proper distance in rear of the iinger-bar, and at the same time elevate the grain and deliver it upon a platform at a proper height to have it conveniently handled by a binder located upon a seat, D.

To the rear ends of the curved fenders or grain-guards Bl B1 of the concave receiver B two arms, S, are rigidly secured, which project backward -l1orizontally,` and serve as supports upon which to secure a platform, C.

This platform() is parallel to the iingenbar A, and it is provided with a follower, P, which `receives an intermittent reciprocatingrmovement across it at right :angles to the line of' draft.

l The follower P is a boardrerected perpen: dicularly to the platform "C, and suitably se cured to a grooved slide, a, which works in .a slot, a. This follower receives its `movements om the shaft F, through certain means, hereinafter explained, so that after a quantity I the combinedpgatherer-and rake. j 4

Two arms, F1 F2, :are secured tothe shaft F, which arms are parallel to each other and at right angles to their shaft, They are made of v sufficient length to extend .nearlyl to the .sur- Y facefof the concave grain-receiver while p'ass'- f ling over it. t The outer extremities of` these arms are connected togetherby means of a rocking bar, G, tok which rake-teeth b b are sei cured in a suitable manner.

On one end of the bar G an arm, c, isse-j cured, from which a pin, cl, projects and plays ina slot, c2, which is made in one end of a vi!v 5 brat'ing lever, H. This lever H is pivoted at d to the arm F1., goutside thereof, and is v ibrated at proper times by a toe, e, and' cam e4,

which latter is affixed permanently to a disk, I, g

on the post Ef. (Shown clearlyin Fig.. 1,) vThe toe e has a stud, el, projecting` from it, Which plays in a slot, c", made in said lever 1H.. I

- It is important to have the rake-teeth ib .perrpendicular to the concave grainreceiver B.E whilev sweeping backward over it, vand also to have said rake-teeth turn up, .asshown in Fig.`

A2, when they are in L,the actof discharging:

grain from the receiver B4 upon the platform for delivering its load.

into the standing grain the toe `e is broughtin contact with its. camsurface e,y and moved so as to act through lever H uponl the rake and) bring its teethV back to a raking.A coinilitiongl again. 'The rake then operates, for a short portion of its backward stroke, as a reel or gatherer, i and presses back the standing swath g to be cut. f t v To the outer end of the-shaft F a short arm,

f, is keyed, and to this arm a slottedlink,

g, is pivoted, which is connected by a pin, g1,

passing through its oblong'rfslot g2 tothe short arm-of a bifurcated lever, JJ. This lever is pivoted tothe side of a rear extension, F', of the post E, as shown in Fig. 1.

The rear'extremityof the lower arm J has aropeor chain, JL, attached tov it, which is carried around a grooved pulley, j, on the eX- tensionBf-.of platform C, thence beneath this platform to and yaround a pulley, p, and thence back again to the grooved slide c, to the bottom of which1 the chain is securely fastened. The rear extremity of the upperarm J has a chain, hf, attached to it, which chain is carried beneath a pulley, i, on extension B2, and thence under platform C to the slide a, .and fastened thereto: t v p l Theslotted link `g, the bifurcated lever J J', .and their connections, with the "slide a of the follower P, are so vadjusted Swith vrelation to the movements 'of the Irake and gatherer that immediately succeeding the delivery of a load of grain upon the .platform C,vv andwhile this rake is v, ascending, the link y] vwill cause the `bifurcated-leverto move the' follower Pracross its` platform .toward the .innerfside thereof;

then, whilefthe-,rake is descending into the `st aruil'ing lswath-'in .front ofthe finger-bar, the .said followerwillbe movedback-again t'o the outer end orsidefof its lplatform C. 1 t
